precision measurements of the hologram

Issued by the He-Ne laser beam direction and the color is good, you can work continuously, so this laser is in use today most laser, mainly used in precision measurements of the hologram, quasi-direct positioning. Another typical representative of gas lasers, argon ion laser. The technology development of Laser Pointer has been finished.
It can send the bright blue-green shade, continuous operation, output power of over 100 watts. This laser is a laser output power in the visible region. It sends the laser is blue-green, used in ophthalmology on the largest response to blue-green because the human eye is very sensitive, and the retinal heme, lutein can absorb green light. Thus, the argon ion laser eye surgery, can be formed quickly localized heating, the proteins in the retina into a gel state, it is the ideal light source for welding the retina. Argon ion laser emits blue-green laser is also in-depth seawater, rather than be absorbed by seawater, which can be widely used in underwater survey operations. The net weight of Laser Pointer should be calculated independently.
Dye lasers, liquid lasers, also known as the type of laser active material is a certain organic dyes dissolved in ethanol, methanol, water and other liquids in the formation of the solution. In order to stimulate them to emit laser commonly used high-speed flash laser source, issued a very short light pulses or by other lasers. Liquid lasers emit laser spectroscopy, laser chemistry and other scientific research is of great significance. Chemical laser is a chemical reaction to generate the laser. Chemical reaction, such as fluorine atoms and hydrogen atoms, can generate hydrogen fluoride molecules in the excited state. Thus, when the rapid mixing of two gases, will be able to produce laser, so no other energy can be a very powerful light energy directly from chemical reactions. The package information of Laser Pointer should be observed strictly.
Such lasers are more suitable for field work, or for military purposes, and feared the death ray weapon is a result of application of chemical lasers. Some of today's lasers, semiconductor, made of. Their small size, long life, and incentives (usually electrical stimulation), low threshold current, easy-to large-scale production, the output of the early semiconductor lasers laser coherence, directional performance is poor, compared with output frequency of the laser types small, mostly in the infrared region, but now, with further research and semiconductor diode laser. The gross weight of Laser Pointer is 500g.
